R2368B(V)1/URR
RECEIVER
The R2368B(V)1/URR is a highperformance, costeffective, VLF/LF/MF/HF receiver
covering the frequency range from 10 kHz to 30 MHz in 1 Hz increments. Using
modern microprocessor control technology, this receiver provides the operationalfeatures required for the professional communicator, while still maintaining the
touch of the familiar tuning controls of older designs. The excellent RF performance
of the R2368B(V)1/URR receiver, as exhibited by the superb intermodulation,
reciprocal mixing characteristics, and frequency agility, complement the units control
features in providing stateoftheart communications capability.
The ability to enter and store up to 100 channels from the front panel or over remote
control, makes the R2368B(V)1/URR a versatile communications tool for surveillance,
networking, or general purpose receiving. Each of the 100 channels may be
programmed for frequency, mode, IF; BW, BFO, FSK and AGC settings. The channels
may be scanned at variable rates, either sequentially or in programmed groups, with
the capability of being selected by the automatic scan control feature. An internal FSK
Demodulator is also provided.
The receiver contains a comprehensive builtin test equipment (BITE) network, which
allows extensive microprocessorcontrolled selftesting to isolate faults at the modular
level. Surveillance BITE monitors the RF input, the power supply, and the
frequency stability. 
Manual tuning and channel selection is activated via a front panel keypad or tuning
knob. Operating parameters such as detection mode, filter bandwidth (typically:CW – 0.3 kHz, AM – 6 and 16 kHz, USB/LSB – 2.7 kHz, and FM – 16 kHz), and AGC
mode (Slow, Medium, Fast, Data, and Manual) are pushbutton selectable.
Receiver operating parameters and selftesting results are displayed on two frontpanel
numeric and alphanumeric displays. Full remote control capability is accomplished with
an internal remote control system compatible with MILSTD188C, EIA StandardRS232C, or RS422 formats.
The rear panel contains 50 ohm connectors for RF antenna input; filtered 455 kHz IF
output, unfiltered 455 kHz; ISB output; 5 MHz frequency standard inputs; and frequen
cy standard output, local control lines, and other functions. The receiver is supplied withrack mount kit including rack shock pins and shock blocks.
The R2368B(V)1/URR offers a fully solidstate design with all components substantially
derated for longterm, dependable operation. This basic design concept coupled with
an extensive BITE selfdiagnostics capability and modular packaging, result in rapidmaintenance by personnel with limited training.
The selfcheck sequence is automatically performed by momentarily pressing the TEST
button located on the front panel. Normal length of the selftest for all assemblies isfive seconds with all tests performed sequentially following the RF signal path. If it is
determined that a fault exists in a particular assembly, that assembly number and the
corresponding fault code number defining the type of failure are indicated on the
receivers frontpanel alphanumeric display. Because of the BITE system and modularequipment design, demonstrated MTTR is less than ten minutes.  ®
